One oft the most challenging procedures in implantology is the predictable and safe regeneration of lateral and vertical bone defects. Besides autogenous bone as the golden standard for jaw augmentation procedures, different biomaterials such as bone substitutes and membranes have shown predictable results especially in lateral grafting applications. In contrast to the patient´s own bone, their use is not accompanied by donor site morbidity, leading to high patient acceptance. Moreover, careful selection from different bone substitutes can focus on specific properties like volume stability, osteogenicity, origin, porosity and ease of clinical application.
However, quality of the recipient site, the osteogenicity of the graft, a transmembraneous angiogenesis of the barrier and the selected healing time are also affecting the predictability of the regeneration outcome.
Newly developed techniques are focussing on graft immobilization and ease of clinical application. They might be interesting additional tools to fulfil the increasing expectations of the modern patient.
